Hide button in Embedded View

Hello All,
I have 2 webdynpro applications. In mt first webdynpro application I have a view in that I have used View container UI element and in that I have embedded my 2nd webdynpro application. This view contains the button called "back" to 1st application.
In my 2nd webdynpro applications there are 2 views Main view and details view.
My requirement is that the "Back" button should be invisible when user goes to the details view of 2nd webdynpro applcation.
Please suggest some solution for this.
Thanks,
Bharat

The first webdynpro will need to have a node which is an 'interface' . The context node that you will create ( to turn of the visibility of the button ) will then be accessible in the 2nd dynpro. It is here then that you set the visible property of the button to false. ( and thus invisible )
The node in the first will need the isInputElement property on to be available in the second. ( to my recollection )
The Internal Web Dynpro component is used by the Embedder Web Dynpro component. The original data is stored in the component controller context of Embedder. To be able to access this data from within a Web Dynpro component of type Internal, the corresponding context elements must first be declared as u201Cmappableu201D in the context of the component interface controller. To do this, the element property isInputElement is set to true
Using External Context Mapping

Creation and Visiblity of Buttons in a View

Hi,
I wish to create buttons in a view without the help of HTML coding.
I implemented the interface IF_BSP_WD_TOOLBAR_CALLBACK and using the methods of it I was able to display the buttons of the view.
But when I tried inserting the above view in a View Set or Over View page I am unable to see the buttons.
Is there any chance of displaying the buttons of the view while embeded in a over view page or over view set without the help of HTML Coding.
Hope I am clear on my question
Regards

Armin Reichert: see TJA311 WebDynpro Part 1 Unit 10, example optional 1 solution 6-3,6-4 -))
my new conclusion is that any UI elements should only be access in wdDoModifyView method
the javadoc discourage from using instance fields not static fields but recommends not to use UIs outside of the method:
Hook method called to modify a view just before rendering.
This method conceptually belongs to the view itself, not to the
controller (cf. MVC pattern).
It is made static to discourage a way of programming that
routinely stores references to UI elements in instance fields
for access by the view controller's event handlers, and so on.
The Web Dynpro programming model recommends that UI elements can
only be accessed by code executed within the call to this hook method.

HIde button on events

Hi,
Can some body elaborate how to hide buttons on events.
Regards
Sameer

Hi,
You can use PPR.
Step 1. create a VO which contains one transient attribute of type boolean
Step 2. Base button rendered property using SPEL
Step 3. Initialize your VO for PPR(inintialization includes insertion of one row and set the attribute as True)
Step 4. In the event handler where you want to hide button just set it false.
Sample code:
//Code to hide button
public void handlePoApproveChangeEvent()
// Get the special, single-row application properties and make the first
// (only) row current.
OAViewObject vo = (OAViewObject)findViewObject("SampleBrowserPVO1");
OARow row = (OARow)vo.first();
// Get the value of the view object attribute with the PO Approval
// status.
OAViewObject poVO = (OAViewObject)findViewObject("PurchaseOrderHeadersVO1");
OARow poRow = (OARow)poVO.getCurrentRow();
String status = (String)poRow.getAttribute("StatusCode");
// Set the application property values based on the PO Approval
// status value.
if ("APPROVED".equals(status))
row.setAttribute("HideButton", Boolean.FLASE);
//Code to initialize VO
public void initializePPRExamplePage()
// Create purchase order header
OAViewObject appPropsVO =
(OAViewObject)findViewObject("SampleBrowserPVO1");
if (appPropsVO != null)
// If the VO already has a row, skip its initialization. Note that
// calling getFetchedRowCount() won't perform a DB hit on a VO with
// no SELECT and only transient attributes.
if (appPropsVO.getFetchedRowCount() == 0)
// Setting the match fetch size to 0 for an in-memory VO
// prevents it from trying to query rows.
// Calling executeQuery() is a small workaround to a known
// BC4J issue that ensures that modified rows in this
// transient view object are not lost after commit. See
// View Objects in Detail for additional information about
// both of these calls.
appPropsVO.setMaxFetchSize(0);
appPropsVO.executeQuery();
// You must create and insert a row in the VO before you can start
// setting properties.
Row row = appProposVO.createRow();
appPropsVO.insertRow(row);
// Set the primary key value for this single-row VO.
row = (OARow)appPropsVO.first();
row.setAttribute("RowKey", new Number(1));
row.setAttribute("HideButton",Boolean.TRUE);
// Initialize the application properties VO (and the UI) based on the
// default PO approval value set on the underlying object.
handlePoApproveChangeEvent();
else
// throw exception
} // end initializePPRExamplePage()
SPEL Parameter:
${oa.myVOName.HideButton}

How to Print the whole view content from a button on the View Layout

Dear All,

How to take print whole view content(lay out) in
webdynpro application.i.e whatever it may be tablecontent or label or inputfield .
Could you send the coded part briefly step by step from the beginning itself i.e
i put the button in the view lay out below the printed parts(label or inputfield) name like show preview .
Now my Question is what should i write in show preview function to take the print in label fields in the webdynpro view lay out
B'cos i am new to webdynpro.Help me
Thx in advance

Dhinakar

Web Dynpro by default does not provide the option of printing the view content.
However still you have a round about way of doing it. Create the an html page similar to the Web Dynpro page. Store the code into a String variable.
String html="<html> ....<scripts>window.print()</scripts></html>";
bytes[] source=html.getBytes();
try{
byte[] b=new byte[1];
IWDCachedWebResource res=WDWebResource.getWebResource(b,WDWebResourceType.HTML);
String url=res.getURL();
}catch (WDURLException e) {
// TODO: handle exception
Now open the url in a new window and that would print the content of the html page.

Launching URL clicking on a button of a view of BSP Component

Hi Gurus,
I have a requirement of opening a webdynpro URL by clicking on a button in a view of a standard BSP component. I have created one transaction launcher and assigned it to a logical link " ZOPP_CRT". In the event handler of the button I have written the following code.
method EH_ONOPP_NEW.
Added by wizard: Handler for event 'OPP_NEW'
data: lv_nav Type ref to if_crm_ui_navigation_service.
lv_nav = cl_crm_ui_navigation_service=>get_instance( me ).
lv_nav->navigate( iv_link_id = 'ZOPP_CRT' ).
endmethod.
I have also checked the following links:

How to hide subfolders in Outlook view in iPhone

Need to hide all subfolders tht comes over from Outlook into my iPhone, takes forever to scroll down when all is showing. Is there a way?

Humm....... you want to hide it in Design View whilst working on the rest of the site?
If that is the case set the menu container <div> to display: none; -
<div id="menu" style="display: none;">This is the content menu</div>
Then either set it to display: block; when you're ready to view it live or remove the style completely.

How to hide content in design view within Dreamweaver?

I have a tabbed content menu that uses some javascript. Everything looks great in Live view, but when I go to design view, all the content goes way beyond the div. How can I make it to where I can hide the content in that div in design view or wrap it completely inside of there? It's really hard to explain which is why I provided some pictures!

Remote Panels not working in embedded viewing mode

Hello,
I'm trying to develop a web version of my project using Labview remote panels. I configured the web server properties as it's described here: http://www.ni.com/white-paper/4791/en/
Currently I'm trying to create the web page on the web publishing tool. However when I select the Embedded viewing mode option I get an "Requested VI is not loaded into memory on the server computer" error on the web page that is created. But if I select Snapshot or Monitor viewing mode option the page is loaded without problems.
I'm using Labview 2013 and oppening the web page in google chrome. The VI from which I'm trying to create a remote panel has some subVIs that show the front panel when called. Is there anything I'm forgetting to configure, or do I need to have any plugins instaled on my browser?
Solved!

There you go, good solution. When doing this remember that you have access to the database on the server. A structure I have found effective is to use the server DB like a dropbox that I write to, and the web server reads from.

HT5361 When inserting pictures in a new mail message using the " photo browser" button I can view and select photos but the " choose " button is gone. What have I done wrong?

When inserting pictures in a new mail message using the " photo browser" button I can view and select photos but the " choose " button is gone. What have I done wrong?

Hi Liz,
Sorry to hear you are having a similar problem. Last night I went to the tool bar at the top of iphoto, clicked on "File", then clicked "Browse Backups" in the drop down menu.    I have an external hard drive that is set up to Time Machine.   The Browse Backups opened the iphoto pages in the Time Machine. I selected a date one day ahead of the day I performed the now infamous update, and it showed my iphoto library as it had existed that day.   I then clicked "Restore Library" at the bottom right corner of the Time Machine screen.   Roughly 2 hours later my iphoto was back to normal.   When I opened iphoto there was a message saying I need to upgrade my program to be compatible with the new version of iphoto(version 9.2.1). I clicked "Upgrade" and within seconds it had done whatever upgrading it needed to do.
The only glitch in the restoration was that it restored the library as it appeared last week, so I no longer had photos I had imported this past weekend.   I simply went back to the Browse Backups in the drop down menu, when Time Machine opened I selected the page showing my pictures from this weekend and again said to Restore Library.   Roughly 45 minutes later the library was restored including the most recent photos.
I am now a happy camper.
I don't know if any of this will be of help to you because your email says you are having trouble with photos imported after the upgrade was performed.   Have you had any pop up notices when you first open iphoto, that tell you you need an upgrade to be compatible with the new iphoto?     If so have you clicked "upgrade"?
Good luck Liz, if you have Time Machine running as a back up to your library, maybe you wil be able to get help there, by following my instructions above.   Otherwise,   good luck with your investigations.   I'd be interested in hearing how you make out.

CHM buttons are not localized in a French project (shows English Contents, Index, Search, Print, Hide buttons)

I opened an old WinHelp project into my new RoboHelp 7. When
I generate the CHM, even with the Project Settings in RoboHelp set
to French and running in a French Windows operating system (MS
Windows XP Pro 2002 SP 2), the CHM output is still in English. The
buttons display in English (Contents, Index, Search, Print, Hide
buttons). The title bar of the CHM also says "HTML
Help" even though the project title in the Project
Settings is "Aide en ligne...".
My Windows Regional Settings through the Control Panel -
Regional Options tab is set French (France). On the Languages tab I
under Text Services and Input Languages, Details button, I selected
French (France) French. On the Advanced tab I selected French. Then
I rebooted.
On the language bar on my Task pane, I selected FR. The CHM
still displays in English.
Please help! I have to produce 4 CHMS in languages other than
English today.
Thanks!

GinaL, would you be able to give us an update? Did the CHM
files look ok on a PC with a true French OS installed?
To avoid having to rewrite everything, I've written the
following info/instructions for my team -- though I'm not yet sure
they're 100% correct:
After I reported this issue to Adobe, they worked on the
problem for several days. They even sent me a new
HtmSingleSourceHtmlHelp.dll file that was supposed to solve the
problem. But it didn't work correctly. No matter what contortions
we put ourselves through, we couldn't get both of these items
correct in the CHM file at the same time, namely:
Index compiled in correct alphabetical order accdg to the
language of the help project.
Correctly translated help title showing in the caption,
regardless of the user's Windows regional settings. (For example,
we wanted "FORMS-Hilfe zu FORMS 5-3" to appear as the caption of
the German version of FORMS help, even if our regional settings
were set to English.)
I think we'd all agree that the index has to be in
alphabetical order. So from what I've seen, this is what we have to
do when compiling a non-English version of help using RH7:
1. Set up the project with the foreign name.
2. Set the language in the project settings. And in the
Project Settings dialog, click Advanced and check out the LNG File
tab to make sure it's using a translated version.
3. Ensure that the Window Caption setting is correct in each
window included in the project. (On RoboHelp's Project tab, open
the Windows folder, double-click each window in turn, and check the
settings.)
4. Set the Language setting in the HHP file to Language=[hex
value for that language]. I found a bunch of them listed on this
web page. Someone else might be able to find a better source:
https://svn.origo.ethz.ch/scoop/es_scoop_60/library/i18n/locale/nls/i18n_nls_lcid_tools.e
5. Change your Windows regional settings to the same language
as the help project. (Reboot if prompted.)
6. Recommended, for safety's sake: Delete the CPD file.
7. Open the project and compile using RH7.
8. Check the index's sort order -- is it in alphabetical
order according to the language of the project?
9. Check the help caption -- make sure it's not "HTML Help".
Note: Any customized buttons in your CHM should appear
correctly translated, but other buttons (Contents, Index, Search)
still appear in English -- at least they do on my PC, even though I
did step 2 above. We need to check whether those buttons appear
correctly when the PC is actually running a true foreign version of
Windows, and not just with temporarily adjusted Windows settings.
OR -- is anyone else able to get these to appear translated in the
CHM file?
Does anyone have anything to add? Other solutions? Easier
procedures? Better results to report?
Thank you
Eileen

Has the play button in album view stopped working?

The play button in album view doesn't work. Hasn't worked for the last two releases. I'm on iTunes 11.1.1. Apple suggested reloading all of my CDs. (Not a viable solution--there are hundreds of them...) They thought it might have something to do with recent changes related to AppleID/iCloud. Also unable to add entire album to up next list. I am able to play from songs view.

Never mind. Found the answer here: https://discussions.apple.com/message/21484039#21484039
User error, but I'm not alone...
